Help setting timing and vac advance
First timer setting timing up….
Decided to replace my mechanical advance distributor with the vac advance unit below from Jegs. My plan is to adjust the mechanical advance of the distributor to about 20 so I will have 16 initial and 36 total and keep the 2 silver springs so timing is “all in” at 2400 rpm. All with vac advance disconnected.
My understanding for the vac advance setup it to put a vac gauge on the manifold port at idle with the car in gear and say it’s 10 inch. So then I adjust my distributor vac advance can till it’s pulling 10 inch (test it with a Mity Vac) and that’s it? Plug it in?
